html - 也可以在手机屏幕上制作视频全屏

Question

好吧，我正在使用以下代码在超大屏幕背景中显示视频，但屏幕上的视频缩小后没有响应并显示空白

<div class="row">
    <div class="videoBgWrapper">
    <video loop muted autoplay poster="assets/images/video.mp4" class="videoBg">

        <source src="assets/images/video.mp4" type="video/mp4">

    </video>
</div>

CSS 如下:

  .videoBg{
        position: absolute;
        top: 0;
        left: 0;
        width: 100%;
        height: 100%;
    }

    @media (min-aspect-ratio: 16/9) {
      .videoBg{
        width: 100%;
        height: auto;
      }
    }
    @media (max-aspect-ratio: 16/9) {
      .videoBg {
        width: auto;
        height: 100%;
      }
    }

但是即使在手机或 ipad 上我怎样才能让它全屏显示

您可以使用 css 样式强制适应视频

  object-fit:fill

请参阅下面的代码片段(在可调整大小的窗口中使用代码)

  .videoBg{
        position:absolute;
        top: 0;
        left: 0;
        width: 100%;
        height: 100%;
    }

    @media (min-aspect-ratio: 16/9) {
      .videoBg{
       
        width: 100%;
        height: auto;
      }
    }
    @media (max-aspect-ratio: 16/9) {
      .videoBg {
       
       width:100%; 
        height: 100%;

        padding:0
      }
    }
body{
  border:solid red;
}
video{
  object-fit:fill

}
